Excessive 10054 Errors. Some network
card/driver combinations randomly cause transmission failures with
outbound data (Remote Connection Reset socket errors). This issue appears
only with specific models of cards. Mail servers are more susceptible to
10054 errors because once the connection is dropped, the entire
transaction is must be resent. Other operations, like file copies etc,
typically accommodate such errors with connection retries, etc. This may be
resolved by using manufacturers drivers. MailEnable has reproduced
this issue and can confirm the following solution:

Open
Start|Settings|Network and Dialup ConnectionsThen select the network
connection that is servicing MailEnable. Right click on it and select
Properties.Click on the Configure button.Click the Advanced
TabChange
the setting for "Optimised for Performance" to Disabled.
